Diagnosis

Manzuma petroae  gen. et sp. nov. is most similar to M. botswana  gen. et sp. nov. in body coloration. The males of M. petroae  gen. et sp. nov. differ in having the clypeus covered with long white hairs with a diamond-shaped patch of brown hairs between the AME and on the upper half of the clypeus in the center ( Figs 170–171, 176–177View Figs 168–181, 186–187View Figs 182–187), while in M. botswana  gen. et sp. nov. the clypeus is covered with short brown scales, medially with a thin vertical stripe of white hairs ( Figs 39View Figs 37–45, 48View Figs 46–51. 46–48). The cheeks in M. petroae  gen. et sp. nov. are covered with yellowish white hairs ( Figs 170–171, 176–177View Figs 168–181) while in M. botswana  gen. et sp. nov. the cheeks have a thin white line running from the ALEs to sides of carapace ( Fig. 38View Figs 37–45). The apical projection (ApP) in M. petroae  gen. et sp. nov. is small, rounded in outline and slightly bent dorsally ( Fig. 158View Figs 154–160), while in M. botswana  gen. et sp. nov. the ApP is large and robust ( Fig. 31View Figs). The females of M. petroae  gen. et sp. nov. differ in the uniform colour of the eye of specimens preserved in alcohol ( Figs 178, 180View Figs 168–181) and short wide stripe just behinf AMEs of live specimens ( Figs 49– 51View Figs 46–51. 46–48), while in M. botswana  gen. et sp. nov. the eye field has a short narrow white stripe just behind AMEs ( Figs 42, 44View Figs 37–45).
